Bearing for scales.



C. E.'R|EDEL. BEARING FOR SCALES. APPLICATION mm NOV. 16. 191-4.

Patented June having flattened overlapping ends riveted together asindicated at d,'the flattened portion having a projecting shoulder 03overlapping the edge of the bearing block A to secure it againstdisplacement. I

It will be obvious that a pair of retalner cases of the form indicatedin Fig. 2 may be employed to support a double bearlng block in place ofthose shown in Figs. 4

and 5.

Having indicated the several parts by reference letters the cease-actian operation of the device will be re d y de t It is well known in thescale art that it is essential to rovide {tor a slight oscillatingmovement of the bearing lp l i Order that it may adapt itself to the.requ rem p the knife edge beari g Of fil 9.5 m the bearing blocksnsnally employed being of agate and very brittle, it is necessary thatthey be supported in a suitable case-or retainer adapted to admit of theosclllatlon of the hearing. The knife edge bearings having a certainlongitudinal movement, 1t is essential that the m e of t p t berestricted within certa n d t the friction due to the end thrust of thepivot be reduced to the minimum; and that 'any foreign mattr a cid ntlly s g down from the w "ghing platfo m onto the hearing may not lodgebetween the end of the knife pivot and its bearing to 1lfeCUtl1eweighing action of thcsc le J In the embodiment shown in Fig. =1, itwill be obvious that the ag te bearing is free to rock upon the ridge Qoivits retaining case, while ill the modification iShO g- 2 the casecarrying the bearing s ee t 7 rock upon the su orting ba r hang lhebearing thus readily idflptsitself t the requirements of the knife ledgepivo' of the scale mechanism. It Will'alsof be apparent that thelodgmcnt of foreign l' i i fll between the end of the pivot and thewalhof the retainer case is avoided by sufficiently 1 spacing the thrustwall of the oflset portion of the case from the end of the bcal'ingtfland that by forn'iing the knife edge pivots with ends tapering to apoint in alinement with the axis of the bearing, the friction due to thecod thrust of the knife edge pivot upon contacting with thewall of theagate bearing case will be reduced to the minimum. llaving thusdescribed my invention 'what Il claim is: V

1. lo a device of the character described, a bearing block grooved toreceive a pivot, a, casc'to receive said block having a wall offset fromthe end of the bearing block to receive the thrust of the pivot, and ahanger for supporting said case.

'2. In a device of the character described, a bearing block grooved toreceive a pivot, an inclosing case for the block provided with a ridgeportion upon which the block is adapted to rock, and a loop forsupporting the case.

3. In a device of the character described, a bearing block grooved toreceive a pivot, an inclosing shell to receive the hearing rovidcd witha transverse ridge upon w rich the bearing block is adapted tQ-tiltwithin the shell, said shell having an end Wall offset from the bearingblock tofr'oceivc the end thrust of the pivot, and a loop adapted tosupport the shell. Y

4. In a dcvice of the character described,

the combination of two bearing blocks grooved to receive knife edgepivots, a pair of cases adapted to respectively support one hearingblock to receive the end thrust of the knife edge pivots, and means forsupporting said cases to maintain the bearing blocks in spaced relationto ea h other.

In a device of the character described, the combination of two agatebearings grooved to receive knit'e edge pivots of a scale mechanism, apair of retaining cases adapted to respectively sup ort the agatebearings, each retaining case aving a transei-se ridge upon which theagate bearing is adapted to tilt, loop han ers adapted to support theretaining cases iaving 0vcrlapping ends riveted together, whereby thebearings are maintained inopposcd spaced rela-' tion to each other.

6. in a device of the character described, an agate bearing having agroove to receive one of the knife edge pivots of a scale mech anism, aretaii'iing'case to receive said agate bearing having a 1 end walloffset-firm the" boa ring adapted to receive the end thrust the knifeedge pivot, a knife edge pivot provided with a tapered end (lesigped tobear against the offset wall of the case an'd a loop for supporting theretaining case.
